Syntegrity Consulting Pvt. Ltd. worked as the Lead Design and Detail Engineering Consultant (DDC) by CSIR-NEERI for two cutting-edge Phytorid based Sewage Treatment Plant (STP) Systems AT Niwari , Uttar Pradesh with capacities of 780 KLD and 500 KLD, respectively. Both projects are based on Phytorid Technology, a nature-based solution that mimics the purification function of natural wetlands.
Phytorid is a subsurface mixed flow constructed wetland system, developed and internationally patented by CSIR-NEERI, Nagpur with the successful demonstration in the field for more than 10 years of continuous operation as a stand-alone sewage treatment system.
